Corrected entry: About halfway through the episode, Wesley comes to the realization that his nanites are causing the malfunctions on the ship, because they escaped from the lab. Shouldn't he at least have know that the nanites had escaped, when he awoke at the beginning of the episode and found that the container had been left open? He might not have known they would become destructive, but he would have known they had escaped.

Corrected entry: As the Enterprise twists so that she is facing away from the matter stream as it is drawn in, Picard orders "reverse engines." That would drive her closer into the stream, not further away.

Correction:Picard orders 'reverse engines' when the ship is oriented just about parallel to the stream. Geordi apparently misunderstands amid the noise of the engine room, answering 'Initiating reverse sequence now', then the ship turns to face away from the stream (apparently the 'reverse sequence' is akin to 'reverse course', not 'reverse engines'). On the bridge, Picard realizes they are drifting rearward into the stream. He doesn't seem upset that Geordi didn't correctly follow the order, but then his focus is on the imminent danger the ship is in. No error.

The cast really are very good friends. At LeVar Burton's wedding in 1992, the best man was Brent Spiner and the ushers were Patrick Stewart, Jonathan Frakes and Michael Dorn. And when Brent Spiner recorded an album (Ol' Yellow Eyes is Back), the backing groups listed as The Sunspots are again the male members of the bridge crew.
